Script Preparation code:

let array = Array.from({length:1000},(i,ii)=>ii)
let iterator = array.values()
function forEach(o) {console.log(o ** 2)}

Tests:

for backwards
for (let {length} = array; length--;) console.log(array[length] ** 2)
for in
for (let i in array) console.log(array[i] ** 2)
for of
for (let o of array) console.log(o ** 2)
for
for (let i = 0, {length} = array; i < length; i++) console.log(array[i] ** 22)
forEach
array.forEach(forEach)
manual iterator
let {done, value} = iterator.next() while(!done) { ({done,value} = iterator.next()) console.log(value ** 2) }
